Q: What's the effect of casting copper?: Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.

Q: Is the cast steel a casting part?: Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast

Q: What are the casting parts tested?: The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.

Q: What is the casting material?: Kdl1588n said in detail, casting a lot of material, steel, iron, aluminum, copper, zinc, etc. can be, valuable, as well as gold and silver, the most common on cast steel and cast iron, cast aluminum and so on.

Q: Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.

Q: When there is no flaw detection for large casting parts, is there any crack inside?: According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified

Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!: Valve sand core mold drying is not in place, excessive water content

Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!: Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over

Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?: Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
